BLOOMFIELD' H. HOWARD, OF WASHINGTON, DISTRXCT OF COLUMBIA, AND ERNEST J. TURNER, 'OF PITTSBURGII, PENNSYLVANIA FEEDER FOR INGOT MOLDS.

Application filed. April 18, 1922. Serial No. 554,834.

To all whom it may concern:

Be it known that we, BLoo'MFmLn H. I'IOWARD and ERNEST J. TURNER, citizens of the United States, residing at, respectively, city of l'Vashington, District of Columbia, and Pittsburgh, county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements in feeders for ingot molds.

The object of our invention is to provide a feeder for ingot molds which can be made very thin and having embedded therein a metal reinforcing element or elements whereby the necessary strength is obtained to withstand the pressure of the molten metal and at thesame time preventing the separation of the feeder should it crack and allow the molten metal to escape from the feeder.

Another object of our invention is to provide a feeder in which the metal reinforcing elements are so arranged as to allow for the expansion and contraction of the feeder, so that it will not crack by the difference in the expansion and contraction of the refractory material and the metal reinforcing elements.

Another object of our invention is to provide a simple, cheap and efficient feeder of this character having certain details of structure and combination of parts hereinafter more fully set forth.

In the accompanying drawings:

Figiiire 1 is a perspective view of the up per end of an ingot mold showing a feeder embodying our inventionapplied thereto;

Fig. 2 is a vertical transverse sectional view of the feeder shown in Fig. 1;

Fig. 3 is a top plan view of a feeder showing a different form of reinforcing lement;

Fig. 4 is a transverse vertical sectional view taken on the line 44 of Fig. 3;

Fig. 5 is a top plan view of a feeder showing another form of metal reinforcing element;

Fig. 6 is a transverse vertical sectional view taken on the line 66 Fig. 5;

Fig. 7 is a top plan view of a feeder showing another form of a metal reinforcing element;

Fig. 8 is a vertical transverse sectional view taken on the line 88 Fig. 7

Fig. 9 is a top plan view of a feeder showing still another form of metal reinforcing element; i

Fig. 10 is a transverse vertical sectional view taken on the line l0-10 Fig. 9;

Fig. ii is a vertical transverse sectional view showing still another form of a metal reinforcing element, and

Fig. 12 is a vertical transverse sectional view showing a still further form of metal reinforcing element.

Referring now to the drawings, 1 represents the ingot mold and 2, the feeder which, as is usually the practice, is supported by the upper end of the mold and in this form of feeder the strengthening ribs 3 form the means of support-- \Vhile we have shown our improved feeder having the reinforcing element of this type, it will be understood that any formof feeder could be used without departing from our invention.

In the form shown in Figs. 1 and 2 of the drawings, we arranged in the feeder between its inner and outer walls 4 and 5 the metal reinforcing element 6 which, as shown, is in the'form of a wire mesh and made in four sections, 6, 7, 8 and 9, which are L-shaped and have their-adjacent ends or edges slightly separated to allow for the expansion and contraction of the same without breaking the feeder.

In the form shown in Figs. 3 and d We have provided a series of vertically disposed reinforcing member 1.0 preferably of sheet metal. and having outwardly extending arms 11 which are arranged in. staggered relation to the arm of the adjoining member whereby the arms of one member extend be tween the arms of the adjoining member, which forms a very efficient reinforcement and yet allows of the expansion and contraction of the metal without cracking the feeder.

Figs. 5 and 6 show the reinforcing element as vertical rods 12 extending from the 'top to the bottom of the feeder.

In Figs. 7 and 8 the reinforcing element are in the form of rod 13; L-shaped and extending around the feeder in a horizontal position, the ends of which are separated to allow for expansion.

In Figs. 9 and 10 we employ the same kind of reinforcing members 14; as shown in Figs. 3 and 4, only they are arranged in a horizontal position in the feeder and are in, sections and do not extend entirely around the feeder but have their ends sepa-' rated so as to allow for expansion.

In Fig. 11 we have shown practically the same arrangement of reinforcing elements only the bars 15 are perfectly plain, having their openings 16 arranged therein.

In Fig. 12 we have shown the reinforcing member 17 in the form of short pieces of wire mixed in the refractory material and then molded.

In each and all of the forms reinforcing members. are molded in the feeder or their refractory material molded around the reinforcing element while in a plastic state and allowed to harden while in a mold and thus in setting the feeder will not crack as the relative construction and expansion of the refractory material and the reinforcing element is compensated for.

What we claim is:

1. A feeder for ingot molds comprising 4. A feeder for ingot molds, comprising a body portion of a refractory material having reinforcing metal formed in disconnectcd sections embedded therein to allow for expansion and contraction of the feeder.

5. A feeder for ingot molds, comprising a body portion of refractory material having reinforcing metal embedded therein and formed in section divided in a Vertical line to allow for expansion and contraction of the feeder.

6. A feeder for ingot molds, comprising a body portion of refractory material, and

metal reinforcing members arranged to al- I low for the vertical and horizontal expansion and contraction.

7. A feeder for ingot molds comprising a body portion of refractory material and metal reinforcing members arranged therein between the inner and outer walls and adapted to allow for'vertical and horizontal expansion and contraction.

A feeder for ingot molds comprising a body portion of refractory material, and disconnected metal reinforcing members arranged the-rein between the inner and outer walls and adapted to allow for vertic'al and horizontal expansion and contraction.

In testimony whereof we afiix our signatnres.
